TRAP FOR THE SUBMERGED OUTLET OF A CATCH BASIN OR THE LIKE FIELD OF THE INVENTION BACKGROUND OF THE INVENTION INCLUDING CERTAIN OBJECTS THEREOF metal trap in the end of the pipe. Such a metal trap often takes the form of a split cylindrical sleeve or collar which is outriggered or cantilevered from a hoodlike baffle that has an inverted U-shaped configuration and is abutted against the wall of the basin at the mouth of the outlet. The trap also takes into account the downward inclination of the pipe with respect to the wall, by pivotally connecting the collar so that it can be angled to the hood at the same inclination as that of the pipe.

While such traps have the advantage that they can be installed in situ, they also have the disadvantage that the installation process requires theuse of mortar, and additional mortaring steps, to close the gap or gaps which are inevitably formed between the collar and the hood, when the collar is pivoted out of a position normal to that of the abutting face of the hood at the wall of the basin. This disadvantage is particularly troublesome in that the gap is normally formed along the upper side of the seam between the collar and the hood, and though this side is readily accessible for the mortaring operation, the operation itself is difficult to execute, because of the difficulty of successfully bridging the gap with the mortar, without the risk of the mortar falling through into the confines of the collar. More- .over, without using mortar, it is seldom possible to achieve a seal between the abutting edges of the hood and the wall of the basin, so that in effect these prior art traps require a bead of mortar around the entire seam between the collar and the hood, and this of course, is a costly addition to the overall expense of installing one at each site where it is needed.

One object of the invention therefore, is to provide a post-installed, telescopically engaged trap of this nature, the snout of which automatically forms a seal with the hood of the trap, about the entire periphery of the snout, notwithstanding the position of the snout with respect to the hood. Another object is to provide a trap of this nature, the hood of which automatically forms a seal with the snout of the trap, about the entire periphery thereof, notwithstanding that the hood may not be abutted with the sidewall of the basin, in the engaged condition of the trap. A further object is to provide a trap of this nature-which requires no further steps for the installation thereof, other than possibly the removal of a small amount of extra material on the trap, by way of trimming it up for use. Other objects include the provision of a trap of this nature which is cheap and simple to manufacture, and contains relatively few parts, all of which can be cut or otherwise formed from inexpensive sheet metal material, if desired. Still further objects will become apparent from the description of the invention which follows hereafter.'

SUMMARY OF THE INVENTION These objects and advantages are realized by a trap of my invention which comprises an inverted U-shaped hood which in use is oriented endwise of the outlet, and the distal upright end opening of which is closed to a point adjacent the bottom opening thereof, but the proximal end opening of which is closed in part only, by an arcuate panel which is connected across the lower portion of the opening in spaced relationship with the bight portion of the hood, so as to define a circular port between the arcuate edge thereof and the adjacent end edge of the bight portion. The hood is mated to the outlet by means of a split cylindrical collar which is oriented so that the split is disposed in the lower part cylindrical portion thereof; and which is telescopically engaged within the port, to seal with the edges of the panel and the bight portion. The collar is also hingedly connected to the legs of the hood, to pivot in the vertical median plane of the proximal upright end opening thereof; and in order to maintain a seal with the bight portion of the hood, the collar has a coaxial part annular brow on the hood-adjacent end of the upper part cylindrical portion thereof, which extends within the hood from said portion, to a point on the opposite side of the hinge between the hood and the collar.

Preferably, the collar is adjustably telescopically engaged in the port, lengthwise the cylindrical axis of the collar.

Also, preferably the distal upright end opening is closed by a pair of relatively upper and lower panels, the upper of which is shiftable in relation to the hood and the lower panel, to open and close the upper portion of said opening for access to the hood therethrough.

In the presently preferred embodiments of the invention, moreover, the brow and the legs of the hood have relatively transversely oriented, but registering slots therein, and the collar is hingedly connected to the hood by means of a pair of pin-like devices which are slidably engaged in the registering slots, and accompanied by means for clamping them to the hood and collar at any one of several selected positions in the slots.

BRIEF DESCRIPTION OF THE DRAWINGS These features will be better understood by reference to the accompanying drawings which illustrate one of the presently preferred embodiments of the invention.

In the drawings,

FIG. 1 is an exploded perspective view of the embodiment;

FIG. 2 is a front elevational view of the same;

FIG. 3 is a rear elevational view of the same; and

FIG. 4 is an operational side elevational view of the embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, it will be seen that the trap comprises an inverted U-shaped sheet metal hood 4 with a substantially semicircular bight portion 6 interconnecting the spaced parallel legs 8 thereof. It also comprises a flanged, sheet metal panel 10 which is rectangular in outline and employed to close the lower portion of the operatively distal or rear end opening 12 of the hood; as well as a notched, sheet metal panel 14 which is cooperatively disposed with the flanged panel 10 to close the remainder of the opening 12. The lower portion of the operatively proximal or front end opening 16 of the hood is also closed, but in this instance the upper edge 18 of the flanged, sheet metal panel 20 employed for closing it, has a part truncated arcuate configuration, and the edge 18 is spaced from the bight portion 6 of the hood, so that together the panel and the adjacent end edge 6 f the bight portion define a substantially circular port 22, in the upper portion of the opening 16. The flanged panels and are interconnected with the hood by mating them to the legs 8 of the hood opposite the respective openings 12 and 16, and then securing the flanges 10 and 20 of the panels to the legs by passing rivets 24 inwardly through apertures 26 in the flanges and thence through registering apertures 28 in the upright edges of the legs 8. The notched panel 14 is also riveted to the hood, but as seen in FIG. 1, it is attached to the rearwardly oriented panel 10 by means of a single rivet 29 which is passed through registering holes 30 and 32, in the lower right-hand corner of the notched panel 14, and the upper right-hand corner of the rearwardly oriented panel 10, respectively, after the two panels are applied over the opening 12 and overlapped at their adjacent horizontal edges. In this way, the panel 14 can be employed as an access door by swiveling it about the axis of the rivet 29, to and from an abutting position within a right angular bracket 34 riveted to the upper right-hand corner of the left-hand leg of the hood in FIG. 1. Also, because of the notches 36 deeply inset into the upper corners of the panel, at downward cants to the vertical edges of the same, it is possible to swivel the panel 14 with a long-handled hook or the like, engaged in one or the other of the notches 36.

The hood assembly 4, 10, 16, 20 is mated to the outlet 38 ofa catch basin 40 or the like, by a split cylindrical collar 42, which is telescoped within the port 22, and hingedly connected to the hood 4 to pivot in the vertical median plane of the front end opening 16 thereof. The collar 42 includes a coaxial part annular brow 44 on the hood-adjacent end of the upper part cylindrical portion thereof. For purposes of mounting the collar, elongated slots 46 and 48 are provided in the brow 44 and the legs 8 of the hood. The slots 46 and 48 are disposed to register at right angles to one another when the collar is coaxial with the port. The slots 46 in the brow are disposed adjacent the axially extending edges 50 of the same, and terminate in the main body of the collar. The slots 48 in the legs are disposed adjacent the front upright edges of the same. The hinge between the collar and the hood is formed by a pair of sheet metal bolts 52 which are inserted through the registering slots 46 and 48 of the same, from inside of the hood, and secured in place by means of washers 54 and wing nuts 56 added thereto outside of the hood. After the collar is telescoped to the desired position within the port, the wing nuts 56 are tightened against the body of the hood to clamp the collar and the hood between the nuts and the head 52 of the bolts. Until such time, however, the collar can be freely adjusted both axially and transversely of the port to accommodate to the angle of the outlet, as in FIG. 4. Moreover, the split 58 in the underside of the collar assures that the diameter of the same adjusts to the diameter and orientation of the outlet; and the brow 44 assures that the collar maintains a seal with the bight portion 6 of the hood. notwithstanding the orientation of the collar in the port 22.

When engaged in the outlet, the trap is held in place by the frictional engagement of the collar therewith.

Normally, the split hood-adjacent ends 60 of the lower part cylindrical portion of the collar, are removed from the same when the outlying end of the collar is so depressed in relation to the hood, to place the ends 60 well within the confines of the hood. This operation is easily accomplished by opening the door 14, reaching within the trap through the upper portion of the opening 12, marking the ends along lines coinciding with the inside surface plane of the panel 20, using the panel as a guide for the marking tool; and then removing the trap from the outlet, tipping the collar up to expose the ends outside the hood, snipping off the ends, and repositioning the collar with respect to the port, before returning the trap to the outlet.
